Difference Between iSIM and eSIM Benefits and More Explained

SIM Cards: Nowadays almost everyone knows about SIM card. Nano and micro cards will also be introduced. But very few people know about Esim. Now in the field of mobile technology there are discussions around eSIM and iSIM. While eSIM is familiar to most people, iSIM is a new entry. Qualcomm recently announced plans to introduce iSIM to smartphones featuring future Snapdragon chips, including the Snapdragon 8 Gen 2 SoC. This development will benefit millions of smartphone users. What is eSIM and iSIM in this context? What is the difference between these? Now let's know about such things.

What is eSIM?

Embedded SIM cards or eSIMs are an integral part of the smartphone hardware. Eliminates the need for a traditional physical SIM. These minuscule chips fit very little space in the device. This allows manufacturers to create compact phone designs without compromising on functionality.

eSIM Activation

To activate an eSIM, one can visit the respective network operator's offline store or use the respective app to initiate an eSIM request. The process of initiating an eSIM may vary depending on the operator.

Phones that support eSIM

Apple Devices: iPhone XR, iPhone XS, iPhone XS Max, iPhone 11 Series, iPhone SE Series, iPhone 12 Series, iPhone 13 Series, iPhone 14 Lineup,. All iPhone 15 models support eSIM. To use eSIM on these, iOS version 12.1 or higher is required.

Android Phones: eSIM support is somewhat limited in Android phones. Galaxy Z Flip, Galaxy Fold, Galaxy Note 20 Ultra, Galaxy Note 20, Galaxy Z Fold 2, Galaxy S21 Series, Galaxy S20, Galaxy Z Fold 3, Galaxy Z Flip 3, Galaxy S22 Series, Galaxy S23 Lineup, Galaxy Z Fold 4 , supported by various Samsung models like the Galaxy Z Flip 4. Also available on Motorola Razr, Motorola Next Gen Razer, Motorola Edge 40, Motorola Edge 40, Razr 40 Series, Nokia G60, Nokia X30, Vivo X90 Pro, Google Pixel 3.

Benefits of eSIM

Physical SIM cards, eliminating the need for trays, occupy less space. Contributes to sleek device designs. eSIMs can be set up and configured from anywhere. No physical SIM card swap required. Some eSIMs have the ability to store multiple profiles, which can switch between different mobile plans or carriers. In addition to compact size, remote provisioning capabilities, eSIMs have enhanced security measures. Protect sensitive data.

Disadvantages of eSIM

A fundamental drawback of eSIMs becomes apparent when users switch devices. There is no easy process of transferring the physical SIM card to a new phone, eSIM activation process and setup process has to be followed every time there is a device change.

 What is iSIM?

iSIM is an evolution from eSIM. Provides the same functionality. But there is one important difference.. the iSIM is completely integrated into the smartphone's chipset. Qualcomm claims that the iSIM is 100 times smaller than a nano SIM card. Currently it is supported by Snapdragon 8 Gen 2 SoC.

Benefits of iSIM

Qualcomm says iSIM technology surpasses eSIMs and nano SIM cards, notably with improved battery life. The most obvious advantage of iSIM is the elimination of the SIM card slot. It provides valuable space that manufacturers can allocate to other components. Devices with iSIM have better resistance to dust, water and become more durable. Provides all the benefits of an eSIM.

 iSIM is the future

Although no phones currently support iSIM, smartphone companies are actively exploring this technology. According to Qualcomm estimates, there will be around 300 million iSIM phones in upcoming Samsung Galaxy models by 2030.
